The Sun Hydraulics RBACTEV (RBACTEV) is a direct-acting, pilot relief cartridge valve designed to remotely control the pressure setting of other pilot-operated valves. This valve is specifically configured with EPDM seals, making it suitable for use in systems with phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The main stage orifice is protected by a 150-micron stainless steel screen, enhancing its durability and reliability in various applications, including load holding. It features a unique floating style construction that minimizes potential binding of internal parts due to installation torque or machining variations. This cartridge valve operates within a cavity T-10A series 1 and has a capacity of 0.25 gpm (1 L/min), with a maximum operating pressure of 5000 psi (350 bar). The response time is typically 2 ms, and the maximum valve leakage at 110 SUS (24 cSt) is limited to 5 drops/min (0.3 cc/min). The adjustment mechanism allows up to five clockwise turns to increase the setting, providing flexibility for various operational needs. The valve hex size measures 7/8 inches (22.2 mm), with an installation torque range of 30\u201335 lbf ft (41\u201347 Nm). Additionally, this model incorporates corrosion-resistant features suitable for harsh environments and can be identified by specific suffixes in the model code for external component protection. This product is ideal for applications requiring precise pressure control and stability under demanding conditions. It offers robust performance characteristics necessary for maintaining consistent operation in systems where load holding and remote pressure control are critical factors.

Description

Direct-acting, pilot relief cartridges are used to remotely control the pressure setting of other pilot-operated valves. Because capacity is limited to pilot flow, these valves should be used with other higher flow valves.

Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
Main stage orifice is protected by a 150 micron stainless steel screen.
Suitable for use in load holding applications.
Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.

For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.

Direct acting or pilot operated - what do I use?	Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
Where would I use a kick-down relief?	One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.
What are the tolerances on pressure settings for Sun's pressure control valves?	Pressure setting tolerances are listed in our Performance Data page. A link to this page can also be found in the Additional Resources tab of the applicable product page.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Can I use a kick-down relief for my system relief?	Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot-operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.
